A leaked supplier document landed on our doorstep this afternoon purportedly showing a rendering of the all-new Cadillac ATS in both sedan and coupe form. According to our sources, neither are real. But dammit, we wish they were.

The document confirms what we already know: the Cadillac ATS sedan is due out in July of 2012 as a 2013 model, and while there's no mention of powertrains, the smart money is on a 2.0-liter turbocharged four-cylinder in the base version and the same 3.6-liter V6 from the CTS fitted to the higher-end model.
